Looks like it.

Why? As the specialized interface gets "inserted" into the specializing unit at
that point, so should the implementation be - and at that point, the operator
Instead, the overload has to be available in the implementation section of the
generic type, /unless/ it is a class or record. That seems odd. You know I
generally prefer consistency over obscure formal differences ;-)
And it's not like we don't already have absurd operator chains without that, see
> * use Generics.Collections
I'd like to stick with fcl units, and rtl-generics seems pretty outdated
compared to your repo?
Of course, the issue itself also occurs with any user code, not just containers.
That kind of lookup means *no* overload on non-object types is available to
generics declared in other units: arithmetic, Implicit, Explicit etc.
Ceterum censeo b32079 esse sanandam.
